Cahill's lawsuit

Weaver was working with John Yob (left) under an arrangement that had paid Yob's firm at least $213,540 since March. When the two left the Cahill campaign, the suit says, Weaver and Yob promised Cahill "that neither of us would go to work for his opponents."

"Even as they made that promise, however, they were actively preparing to break it," says the suit.
